Apple uses USB-C in latest notebooks and now in iPad Pro. I am surprised they didn't implement this yet in latest iPhones, seems strange to introduce iPhones with lightning connectors and only a few weeks alter iPad Pro with USB-C. I expect next year iPhone will have USB-C too.

I could be wrong, but I believe these ports were invented by Apple and are now obsolete or will be obsolete soon

Lightning (IIRC was introduced in 2012 and I suspect it will be discontinued in 2019)
MagSafe (started when??? and seems dead as of 2018)
Thunderbolt (introduced in 2011? and seems dead as of 2018)
FireWire (introduced in lats 1990s and dead as of late 2010, OK this lasted 20 years)
30 Pin iPod/iPhone/iPad connector (introduced in early 2000s and dead as of early 2010s, lasted about 10 years)
ADB (not sure when it started, but my B&W 1998 G3 still had an ADB port I believe)
ADC (Apple Display Connector)

There were probably other types of ports that Apple used but I may not be familiar with those. I believe when PCs were using VGA, Apple had a slightly different connector but it was mostly the pinout that was different, I think with the right adapter you could connect a PC monitor to a Mac and vice versa. SCSI was also used by some PCs, I don't think that was Apple specific.

AAUI, their interface to ethernet. I think I still have the adapter somewhere.

And let's not forget their own VGA connector.

Right, I think he mentioned that; Apple used a 7/8 pinout, while PCs were 5/5/5.

The one I remember was HDI-45, a video output on the original PowerMacs (61xx/71xx/81xx) that only worked with one monitor, the Apple AudioVision 14 CRT. During my time at an Apple Authorized Store, we sold many, many of these adapters to people who wanted to connect any other VGA monitor to those PowerMacs, for a not cheap price in the ballpark of $40 each IIRC...

This adapter also ensured that you could not push your computer closer than 4" to any wall.

Intel created Thunderbolt as an optical technology.
Apple created the mini DisplayPort connector for the MBAir.

Apple successfully convinced Intel to make the TB protocol work over copper, using Apple's mini-DP connector. Separately, the PC standards people (IECC?) decided to adopt Apple's mini-DP connector as a DP standard and you still see it on MS Surfaces.

The decision was made for TB3 to use the USB-C connector but the protocol is still the same TB (but faster), just now with a third different physical connector.

PlainTalk Mic connector. Was a longer version of a standard 3.5mm / 1/8" plug, with the tip getting 5v power. At one point I tried really hard to find a jack compatible with this plug, without success.

Lightning connectors are thinner than USB-C connectors. Apple's phones have gotten thinner, which doesn't fit with going to USB-C.

Apple has pushed "thin" on the iPad line too. The iPad Pro is aimed at a different market.

I can't see Apple putting standard USB-C connectors on iPhones. So, will we get an updated Lighting connector that's a "mini" version of USB-C?
